第七题地址：http://www.pythonchallenge.com/pc/def/channel.html
根据提示，我们看到<!-- <-- zip -->，试一试之后发现可以把channel.html改成channel.zip，然后下载得到一个zip文件。
打开zip文件，其中的readme.txt，我们得到如下的提示
welcome to my zipped list. hint1: start from 90052 hint2: answer is inside the zip
我们找到90052.txt
Next nothing is 94191
看到又是nothing，并且指向了94191，很明显是下一个文件。
import zipfile
import re
filename = 'C:\Python27\channel.zip'
def process():
file_list = zipfile.ZipFile(filename)
regex = re.compile(r'(\d+)$')
nothing = '90052'
try:
while True:
fn = '%s.txt' % nothing
print file_list.read(fn, 'r')
nothing = regex.search(file_list.read(fn, 'r')).group()
except:
pass
if __name__ == '__main__':
process()运行完，得到如下结果

最后得到Collect the comments，再查看zipfile模块，发现ZipFile.getinfo()返回一个ZipInfo对象，包含了文档中相应的文件信息，里面有comment，表示文档说明。
修改上述代码
import zipfile
import re
filename = 'C:\Python27\channel.zip'
def process():
file_list = zipfile.ZipFile(filename)
regex = re.compile(r'(\d+)$')
nothing = '90052'
comments = []
try:
while True:
fn = '%s.txt' % nothing
comments.append(file_list.getinfo(fn).comment)
nothing = regex.search(file_list.read(fn, 'r')).group()
except:
print ''.join(comments)
if __name__ == '__main__':
process()把comment都存在一个list中，然后最后输出所有的comment。得到如下的图形
**************************************************************** ** ** ** OO OO XX YYYY GG GG EEEEEE NN NN ** ** OO OO XXXXXX YYYYYY GG GG EEEEEE NN NN ** ** OO OO XXX XXX YYY YY GG GG EE NN NN ** ** OOOOOOOO XX XX YY GGG EEEEE NNNN ** ** OOOOOOOO XX XX YY GGG EEEEE NN ** ** OO OO XXX XXX YYY YY GG GG EE NN ** ** OO OO XXXXXX YYYYYY GG GG EEEEEE NN ** ** OO OO XX YYYY GG GG EEEEEE NN ** ** ** **************************************************************** **************************************************************
it's in the air. look at the letters.
还没结束，我们再回看输出，得到组成hockey的字母组合是oxygen。
url结尾单词改为oxygen，跳转到下一个puzzle。

以下zipfile模块的内容为转载
class zipfile.ZipFile(file[, mode[, compression[, allowZip64]]])
创建一个ZipFile对象，表示一个zip文件。参数file表示文件的路径或类文件对象(file-like object)；参数mode指示打开zip文件的模式，默认值为‘r‘，表示读已经存在的zip文件，也可以为‘w‘或‘a‘，‘w‘表示新建一个zip文档或覆盖一个已经存在的zip文档，‘a‘表示将数据附加到一个现存的zip文档中。参数compression表示在写zip文档时使用的压缩方法，它的值可以是zipfile. ZIP_STORED 或zipfile. ZIP_DEFLATED。如果要操作的zip文件大小超过2G，应该将allowZip64设置为True。
ZipFile还提供了如下常用的方法和属性：
ZipFile.getinfo(name)
获取zip文档内指定文件的信息。返回一个zipfile.ZipInfo对象，它包括文件的详细信息。
ZipFile.infolist()
获取zip文档内所有文件的信息，返回一个zipfile.ZipInfo的列表。
ZipFile.namelist()
获取zip文档内所有文件的名称列表。
ZipFile.extract(member[,path[，pwd]])
将zip文档内的指定文件解压到当前目录。参数member指定要解压的文件名称或对应的ZipInfo对象；参数path指定了解析文件保存的文件夹；参数pwd为解压密码。下面一个例子将保存在程序根目录下的txt.zip内的所有文件解压到D:/Work目录：
import zipfile, os
zipFile = zipfile.ZipFile(os.path.join(os.getcwd(), 'txt.zip'))
for file in zipFile.namelist():
zipFile.extract(file, r'd:/Work')
zipFile.close() ZipFile.extractall([path[, members[, pwd]]])
解压zip文档中的所有文件到当前目录。参数members的默认值为zip文档内的所有文件名称列表，也可以自己设置，选择要解压的文件名称。
ZipFile.printdir()
将zip文档内的信息打印到控制台上。
ZipFile.setpassword(pwd)
设置zip文档的密码。
ZipFile.read(name[, pwd])
获取zip文档内指定文件的二进制数据。下面的例子演示了read()的使用，zip文档内包括一个txt.txt的文本文件，使用read()方法读取其二进制数据，然后保存到D:/txt.txt
#coding=gbk
import zipfile, os
zipFile = zipfile.ZipFile(os.path.join(os.getcwd(), 'txt.zip'))
data = zipFile.read('txt.txt')
(lambda f, d: (f.write(d), f.close()))(open(r'd:/txt.txt', 'wb'), data) #一行语句就完成了写文件操作。仔细琢磨哦~_~
zipFile.close() ZipFile.write(filename[, arcname[, compress_type]])
将指定文件添加到zip文档中。filename为文件路径，arcname为添加到zip文档之后保存的名称, 参数compress_type表示压缩方法，它的值可以是zipfile. ZIP_STORED 或zipfile. ZIP_DEFLATED。下面的例子演示了如何创建一个zip文档，并将文件D:/test.doc添加到压缩文档中。
import zipfile, os zipFile = zipfile.ZipFile(r'D:/test.zip'), 'w') zipFile.write(r'D:/test.doc', 'ok.doc', zipfile.ZIP_DEFLATED) zipFile.close()
ZipFile.writestr(zinfo_or_arcname, bytes)
writestr()支持将二进制数据直接写入到压缩文档。
Class ZipInfo
上面的那个问题中，运用到了ZipInfo对象的相应属性：
ZipFile.getinfo(name) 方法返回的是一个ZipInfo对象，表示zip文档中相应文件的信息。它支持如下属性：
ZipInfo.filename： 获取文件名称。
ZipInfo.date_time： 获取文件最后修改时间。返回一个包含6个元素的元组：(年, 月, 日, 时, 分, 秒)
ZipInfo.compress_type： 压缩类型。
ZipInfo.comment： 文档说明。
ZipInfo.extr： 扩展项数据。
ZipInfo.create_system： 获取创建该zip文档的系统。
ZipInfo.create_version： 获取 创建zip文档的PKZIP版本。
ZipInfo.extract_version： 获取 解压zip文档所需的PKZIP版本。
ZipInfo.reserved： 预留字段，当前实现总是返回0。
ZipInfo.flag_bits： zip标志位。
ZipInfo.volume： 文件头的卷标。
ZipInfo.internal_attr： 内部属性。
ZipInfo.external_attr： 外部属性。
ZipInfo.header_offset： 文件头偏移位。
ZipInfo.CRC： 未压缩文件的CRC-32。
ZipInfo.compress_size： 获取压缩后的大小。
ZipInfo.file_size： 获取未压缩的文件大小。
下面一个简单的例子说明这些属性的意思：
import zipfile
zipFile = zipfile.ZipFile('C:\Python27\channel.zip')
zipInfo = zipFile.getinfo('90052.txt')
print 'filename:', zipInfo.filename
print 'date_time:', zipInfo.date_time
print 'compress_type:', zipInfo.compress_type
print 'comment:', zipInfo.comment
print 'extra:', zipInfo.extra
print 'create_system:', zipInfo.create_system
print 'create_version:', zipInfo.create_version
print 'extract_version:', zipInfo.extract_version
print 'extract_version:', zipInfo.reserved
print 'flag_bits:', zipInfo.flag_bits
print 'volume:', zipInfo.volume
print 'internal_attr:', zipInfo.internal_attr
print 'external_attr:', zipInfo.external_attr
print 'header_offset:', zipInfo.header_offset
print 'CRC:', zipInfo.CRC
print 'compress_size:', zipInfo.compress_size
print 'file_size:', zipInfo.file_size
zipFile.close()
# result
filename: 90052.txt
date_time: (2006, 6, 6, 6, 6, 6)
compress_type: 8
